NEW YORK (CNNMoney.com) -- Microsoft chairman and co-founder Bill Gates boasted to CNN that Vista, Microsoft's widely anticipated new version of its Windows operating system, will make the personal computer the "place where it all comes together" for multimedia applications such as photos, music and videos.

Gates explained several of Vista's key new features, including controls that let parents monitor what Web sites their kids have viewed as well as the time spent on the computer.

Gates also showed some of the features for editing digital photos and videos. "We're making the PC the place where it all comes together," Gates said, adding that people using Vista will be able to view content from their computer on their TV.

Gates bristled at the suggestion that Vista had some similarities to Apple's (Charts) OS X operating system for Macs. "No no no. There are whole areas where we've innovated," Gates said during the interview.

Some tech experts have suggested that consumers do not need to upgrade to Vista if they did not plan on buying a new computer within the next few years.

But Gates said that it is relatively easy for people to upgrade from XP to Vista as long as they have bought a computer recently and that it would make sense to upgrade in order to enjoy the operating system's new features.

"If you are not going to buy another machine for another few years why should you not get the benefits from all the richness here?" he said.

The company plans to spend $500 million to promote Vista, a figure that one analyst said was probably a record for the company but not "shocking."

"I'm sure this is the most they've ever spent launching a new product," said Rick Sherlund, an analyst with Goldman Sachs, adding that Microsoft will probably have marketing help from PC manufacturers, such as Dell (Charts) and Hewlett-Packard (Charts), who will be seeking to sell new machines that run Vista.

Goldman Sachs' Sherlund does not own shares of Microsoft but his firm has done investment banking for the company.
